Project done by: Mia Cothran and Lana Spieler. AIM: Does the amount of detergent change the amount of froth the detergent makes. RESEARCH: How the detergent affect the froth. HYPOTHESIS: I think that the more detergent there is in the water the frothier it will be, because you can mix more water into the detergent to create more froth. VARIABLES: INDEPENDENT: amount of detergent. DEPENDENT: amount of froth. CONTROLED: same amount of water and type of detergent. MATERIALS: Water APPARATUS: Beaker, glass rod, and dropper. CHEMICALS: Soap PROCEDURE: Step 1: gather materials. Step 2: pour 1.5 tbsp. of soap into 500 ml of water in a beaker. Step 3: stir soap and water with a glass rod for 3 min. Step 4: record answers/data. Step 5: pour out liquid and suds. Step 6: pour in 500 ml water and 2 tbsp. of detergent into beaker and stir with glass rod for 3 min. Step 7: record data/answers. Step 8: pour out liquid in beaker and add 500 ml of water and 3 tbsp. of detergent and stir for 3 min. Step 9: record data and compare all results. Step 10: do report properly. DIAGRAM:

CONCLUSION: My experiments results show that the more detergent you put in water the more froth the there will be because the detergent will soak up more water making it expand and become more light and bubbly. REFLECTION: Our project was very successful because our hypothesis came true as well did our question and what we wanted to find out. Our group of two Mia and I worked very well together and I think that we are happy that we were able to do our experiment successfully and without any flaws. SAFETY PROCEDURE: 1.Keep soap out of your eye. 2.Don’t play around in the lab.
